Coherent Radiation of the Channelling Positron (Electron)

Abstract

Abstract Coherent radiation of a relativistic positron (electron) in a crystal is considered in the case of planar channelling. The wave function of the particle is found, the cross‐section of the process is calculated, and the evaluation of the radiation intensity is given. The coherent X‐ray radiation spectrum is analysed and the observation possibility of the complex and anomalous Doppler effect in this condition is shoun.
